ACTUATING DEVICE FOR COUNTERS Filed Aug. 1'7, 1928 Patented July 19, 1932 UNITED STATES PATENT OFFICE OSCAR CHARLES ROESEN, OF BROOKLYN, NEW YORK, AND ISIDOR TORNBERG, FLAIN- FIELD, NEW JERSEY, ASSIGNORS TO WOOD NEWSPAPER MACHINERY CORPORA- TION, OF NEW YORK, N. Y'., A CORPORATION OF VIRGINIA Y ACTUATING DEVICE FOR COUNTERS Application filed August 17, 1928. Serial No. 300,368.

This invention relates to the actuating device or counter unit to be used as an actuating device to impart electric impulses to a master controller'or accumulator for counting the number of products from a plurality of machines andstopping the machines when a predetermined numberhave been delivered from the entire group.

We have previously described such a device in our joint application, Serial No. 224,567, filed October 7, 1927. In that case there was such a counting unit or actuator connected with eachof the folding machines of the press or presses, each one being idle when its folder was idle.

The principal objects of this invention are to reduce the number of those units, specifi cally by providing one connected with two folders, thus reducing the complication and cost of installation and repairs and further to simplify the construction; to provide a construction of this unit which will enable it to operate with either one of the two folders with which it is connected absolutely at the speed of that folder and to operate with both of them if they are in action without any failure to impart the necessary impulses to show the delivery of the products from each of the folders and from both of them and to provide, as in our above application, for correct counting when running collected or noncollected products.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing in which Fig. 1 is a diagrammatic end view of two folders showing the connection with a single counter unit in accordance with this inven tion;

Fig. 2 is an end view of the counter unit;

Fig. 3 is a sectional view of the drive on the line 33 in Fig. 1;

Fig. 1 is a central longitudinal sectional view of the counter unit by itself;

Fig. 5 is a diagram of the electrical connections pertaining to the counting unit alone, and Fig. 6 is a view similar to part of Fig. 5, showing the switch open.

As stated above, the above mentioned apeachrotation of the box.

plication relates to the provision of two folders as A and B in Fig. 1, each with an individual counter unit which is arranged to impart electric impulses to a master counter or accumulator, not shown herein, so that the latter will always show the total number of products of the two folders or in fact of a large number of them.

For the purpose of providing only one of thesecounter units for two folders we have shown the two main folder shafts as provided with worms 61 operating worm gears 62 keyed to shafts 63 and 64 respectively and geared in ratio l to 10. Theseshafts extend intoa differential box 59 and on the end each one haskeyed to ita mitre gear 67. These two mitre gears both mesh'with "another pair of mitre gears 68 loosely mounted on a cross stud 69 which has its bearings in the box 59. This constitutes a differential.

On this box. are two cams located directly opposite each other for closing contacts 66 in an electric circuit twice during On the box 59 is a plate 70 rotating with the box and'c'arrying asingle cam 75,'for closing a contact 74, once during each revolution. The two cams are used to make twice as many contacts when non-collected products are run, in comparison with the situation in which collected" products are run. This arrangement is made in order that the count may represent the actual number of papers delivered, instead of the number of revolutions.

Referring to the wiring diagram, it

78 which can be kept closed by the'weight of arms '7 9 if-placed in the position shown in full lines in the drawing, but if thrown up out of engagement with these contacts, as"

- for example, to the dotted line position shown in Fig. 1, these contacts will open. It will be understood that all the contacts 66, 74: and

be controlled solely by the cam 75 and will be closed Once during each revolution of the" winbe seen; that there are-two spring contacts box 59. This cam 75 is shown as located in axial alignment with one of the cams 65.

When only one of the two folder units is running the box 59 rotates at a given ratio with the folding cylinder or at one half the speed of the driving shafts 63 and 64:, the number of cams provided producing the correct number of electric impulses on the circuit 82.

When, however, bothfolders are operated at one time, the box will rotate at twice the original speed or'at the same speed as shafts 63 and 64, thereby producing twice as'many impulses as before. Thisautomatically doubles the number of impulses, when both folders are running, than take place when only one folder is employed.

This. differential arrangement obviates the necessity for doubling the number of elements required in the production controller, the doubling up action of the differential being employed in its stead.

The switch 78 described in the said patent application may be employed as heretofore with the lever 7 9 which controls the collecting mechanism of the folder. Thus, when collected products are-run over one of the folders one impulse per a given number of revolutions of the folding cylinder is transmitted. When a non-collected product is run over one of the folders two impulses per the same number of revolutions are transmitted.

When collected products are run over both folders two impulses are likewise transmitted and when both folders are employed with noncollected products four impulses aretransmitted in the controlling mechanism.

Although we have illustrated and described only one form ofthe invention we are aware of the fact that modifications can be made therein by any person skilled in the: art with vice comprising a box, shafts operated by 1 said machines and extending into the box, and

a differential connected with the two shafts and comprising gears supported in said box,

the combination of an electric circuit having therein a contact, a pair of oppositely placed cams on the box for closing said contact twice during each revolution of the box, whereby electric impulses areimparted to the circuit, a single cam carried by the box, a contact parallel with the first-named contact in the circuit in position to be closed by the single cam once during each revolution, the single cam being. arranged in the same relative position as one of the double cams so that normally the closing of its contact will not affect the number of impulsesimparted to the circuit. 7 I

In testimony whereof we have hereunto affixed our signatures.
